assume that there is a heat source in a room and there is ventilation .Inlet and outlet is present .Because of the heat source air inside the room gets heated and moves out .How to do we know whether we have to apply pressure inlet and outlet condition at the inlet and outlet or apply velocity boundary condition at the inlet and outlet
